Luck enhancers have no effect on the chances of obtaining this scroll as a drop, although a Champion scroll enhancer does. When in your inventory, the enhancer gives a 20% higher chance of receiving a scroll. The enhancer has 250 charges to start with, and one charge is used whenever you kill a creature that has a chance of dropping a champion scroll. It will disappear when all the charges have been used up.

Another good place to collect the scroll is by killing the Dried zombies in the Ruins of Ullek. You can set up a Dwarf multicannon in the centre of the area with the zombies, and use Revolution with any combat style. This yields a high kill count per hour with little effort.
